Apprentices are a rank on BlogClan. In real life, they currently attend middle school or their country's equivalent. They may have a mentor, although there's not really any bonus to having one. When they finish middle school, they become warriors.
Apprentices are just like any other person on BlogClan, except they have the word 'paw' in their names.
Apprentices are often looking for mentors. But there are so many more apprentices than warriors! Most apprentices will have to wait a long time until they get a mentor. Recently, there have been many more available mentors on BlogClan, and the waiting apprentice list has gotten steadily shorter.
